Where is mankind positioned within the Universe? What is going on within atoms? was once Einstein continuously correct? can we locate extraterrestrial existence within the close to destiny? And what might be performed approximately international warming? Sébastien Balibar, a number one authority in physics, makes use of illuminating tales from his personal existence to reply to the main fascinating questions within the actual sciences at the present time. The Atom and the Apple considers facets of our environment--the issues we see round us, yet seldom actually understand--and exhibits that technological know-how could be a thrilling experience grounded within the phenomena of the day-by-day world.
Balibar examines twelve difficulties spanning the frontiers of physics, and he devotes a bankruptcy to every factor. He appears at chaos idea, cosmology, fluid mechanics, and climatology. He explains how we found the age of the Earth, how we all know the Universe is increasing ever extra quickly, and why the spiral styles of pinecones and sunflowers are regarding the Golden Ratio in arithmetic. He scrutinizes how the collective habit of atoms ends up in such impressive effects as lasers, superconductors, or superfluids. As Balibar invitations us to understand the physics hidden in the points of interest and sounds of the wildlife, he additionally recounts the stories of his adolescence and occupation that have been pivotal to his lifelong ardour for science.
Written for common readers, The Atom and the Apple explores attention-grabbing features of our international, and demonstrates why the pursuit of medical wisdom is easily worthy everyone's time, despite clinical background.

We see how much the interpretation of a measurement in physics depends on the model being used. Rutherford would nevertheless use helium nuclei, the “alpha” particles emitted by certain nuclear reactions, to demonstrate that the nucleus of an atom is much smaller than the atoms themselves. pdf WBG Soft Proof 4/21/08 2:51:46 PM Pg 33 I AM RADIOACTIVE reactions, was a good one. 5 billion years. We were thus approaching the truth which has today been established. One day in 1994, while reading Jean Jacques’s Confessions of an Ordinary Chemist, I came across a magniﬁcent quote from Victor Hugo’s William Shakespeare.
Another hypothesis has been proposed, according to which the Earth, rotating rapidly on its axis, lost some of its surface after elongating. It doesn’t seem, however, that the rotational speed of the Moon is compatible with this hypothesis. It has also been proposed that the Earth might have captured a foreign object which was passing by and kept it in orbit; but then, if this object was already part of the same solar system, why didn’t it contain the same kind of metallic core as the Earth? Now, in our day of computers and complex calculations, the idea proposed by Hartmann and Davis in 1975 has apparently been accepted: the Moon is a result of a titanic collision between the newly formed Earth and an object the size of Mars (around 6,800 km in diameter).

So what is it about that blue brigade, then, that makes me so indignant, even today? And can I manage to describe and explain this “condensation” invented by Einstein without equations? Is it possible to explain in plain English the nature of a discovery made in the arena of quantum physics—a branch of physics renowned for being so completely removed from our daily experience?
